Need a macro that will forward an email as an attachment to an address, on click or auto

Hi,

I have been working on a project, and have one last piece of the puzzle I need your help with.

Basically this element requires any email where the subject contains "apple" for example to be automatically forwarded as an attachment to another email address (which will always be the same address).

I have tried making rules in outlook that will look for inbound messages containing that, and forwarding, but for some reason this simply does not work (I am unsure why, but have tried on multiple accounts and computers, and it just won't work with our setup!)

I was wondering if it would be possible to write a macro script that works within outlook that would automatically pick up emails with "apples" in the subject and forward them on. Is this at all possible?

In the event that it isn't, we could probably just work with a macro button that would sit on the ribbon of every message that arrives in the inbox, and this process would forward the given email as an attachment to the specified email address.

If this could be automatic it would be so much better, but if it is simply not possible, the button process would work.

Could anybody PLEASE help me with this! I'm tearing my hair out!

Thanks
